Tasmania Police's professional standards body will lead an investigation into the death of a person whose body was found in a vehicle following a police pursuit on Monday.
Police believe the deceased is the man wanted over the alleged shooting of two police vehicles a fortnight ago, 33-year-old Brighton man Robert Greig.
Police set up road spikes on Monday at the intersection of Nugent and Kellevie Road after a member of the public reported seeing Mr Greig's Holden Colorado on the Arthur Highway in the state's south-east.
